List,
I was reading some of the history of mechanical clocks and was astonished to
see that one guaranteed its accuracy to 2 milliseconds per day! (And it was)
Now this same clock when tested with modern equipment tested to be accurate to
200 micro-seconds per day. Astonishing!
This got to wondering how the heck they were able to calibrate a clock to
milliseconds per day back then?
And as extension to that question, how do they prove the accuracy of F1 or
other similar time standards?
Regards,
Perrier
